I have a 2011 V6 with 85000 miles on it and I am almost certain the heater core is clogged from researching online. I am having trouble reaching or even following the two heater core lines so I can just flush that part of the system. The radiator seems fine. The driver left vent is the hottest and the passenger right vent is flat out cold with heat cranked. I am almost certain it is the heater core form everything I have read. I would like to try to self flush it, in other cars I have seen it successfully unclogged with compressed air, but I really only want to disconnect the heater core and use its hoses and not mess with anything else, can anyone tell me where they are located.
